What This Study Found

Collagen peptide group saw a 2.4 kg increase in fat-free mass and a 1.2 kg decrease in fat mass compared to placebo.

Key Numbers

How They Did This

A randomized controlled trial with 97 participants divided into three groups receiving different supplements during a 12-week resistance training program.

Why This Research Matters

This research highlights the potential of collagen peptides as a supplement for improving body composition and muscle strength, particularly in middle-aged men who are untrained.

What This Study Doesn't Tell Us

The study focused only on middle-aged, untrained men, limiting generalizability to other demographics.
